Apple has released the second iOS 9.2 beta for iPhone, iPad, or iPod Touch to those who are enrolled into Apple’s developer program. iOS 9.2 beta 2 carries a build number 13C5060d. You can find the download links to iOS 9.2 beta 2 below, but it requires Apple Developer Program.

iOS 9.2 brings some new features and improvements and bug fixes to the Safari View Controller, which is the window that opens up when you click a link within an app. It also supports 3rd party action extensions. The new addition includes edge swipe-to-dismiss for Safari View Controller. Here’s the official changelog for iOS 9.2 beta 2:

Apple Watch
If you un-pair and re-pair your Apple Watch, the stocks glance may be missing.
Apple Watch may be unable to sync music.

Audio
Resolved an issue impacting audio quality when playing audio over USB with some car stereos.

Networking
Explicit Congestion Notification (ECN) is now enabled by default on Wi-Fi and on select carriers. This is designed to reduce network delays and reduce packet loss.
The ability to synthesize NAT64 IPv6 addresses from IPv4 literals was added to getaddrinfo.

Safari
SFSafariViewController now supports 3rd party Action Extensions. Any Action Extension that works in Safari will also work in SFSafariViewController.
Long tapping the Reload button in Safari View Controller now gives options to Reload Without Content Blockers and Request Desktop Site, like in Safari.
Safari View Controller can now be dismissed using an edge swipe. You must rebuild your app against the iOS 9.2 SDK or later in order to take advantage of this new behavior.

In the first iOS 9.2 beta, Safari View Controller was the main focus and it continues to be so with the second beta as well.

iOS 9.2 beta 2 is now available as an Over-the-Air (OTA) update. If you are running iOS 9.2 beta version, you can easily update to this latest beta by going into Settings > General > Software Update.
